10% is a phenomenal rate of return right now.
i.e. 0% after accounting for inflation. Oh God everything's going straight to hell.
Trying to race automation to the cost bottom is an exercise in futility; it's a race humans will not win. The only ones that benefit from it are the employers that get cheaper labour faster as a result.
Not only the employers. Consumers also benefit from the lower prices resulting from cheaper costs of production. Basically the only ones that are worse off are those people who did the jobs that are now automated. That's only in the short-run since increased production always ends up leading to new jobs, be it in that industry in other capacities or in other industries that wouldn't have existed otherwise (consider whether we'd ever have something like a computer industry if 90% of the population were still farmers as in 1862).
